ERROR: Failed building wheel for pyzmq on OpenBSD

[joyboy67]

This is a pyzmq bug

• This is a pyzmq-specific bug, not an issue of zmq socket behavior. Don't worry if you're not sure! We'll figure it out together.

What pyzmq version?

latest

What libzmq version?

none

Python version (and how it was installed)

3.10.13

OS

OpenBSD 7.3

What happened?

doas pip3 install pyzmq

Does /usr/local/include/zmq.h exist?

[joyboy67]

Does /usr/local/include/zmq.h exist?

Yes !

[minrk]

Can you run a build with SKBUILD_CMAKE_VERBOSE=1 to show the compile commands?

[minrk]

and pkg-config --cflags libzmq?

[minrk]

(btw, if you need a short-term workaround, you can ignore the discovered libzmq with: ZMQ_PREFIX=bundled which will tell pyzmq to build libzmq as a static library)

[joyboy67]

and pkg-config --cflags libzmq?

$ SKBUILD_CMAKE_VERBOSE=1
$ pkg-config --cflags libzmq
-I/usr/local/include

Ok 👍 I need pyzmq as dependency for install @basicswap

How did you install libzmq?

Can you run one more time after

export CMAKE_ARGS="-DCMAKE_VERBOSE_MAKEFILE=1 -DCMAKE_EXECUTE_PROCESS_COMMAND_ECHO=STDOUT"

?

I just setup a fresh openbsd 7.6 vm with pkg_add zeromq and it successfully found libzmq and worked fine, so I'm not sure why it's not finding your zmq.h.

same error :/

Oh ok, I'm on 7.3 and I have also zeromq :

$ pkg_info -Q zeromq
zeromq-4.3.4p0 (installed)
$ pkg_info -Q libzmq 
p5-ZMQ-LibZMQ3-1.19p2 (installed)

[minrk]

Sorry, that last command was supposed to produce more output for debugging, not fix anything. Can you share the output?

[minrk]

How did you install Python, as well?
